Suggest Remedy For Lower Back Pain After Lumbar Spinal Fusion

I had lumbar spinal fusion in December and felt better for about a month. Beginning in February things have gotten worse. More lower back pain, hip pain, leg pain, numbness in my feet, shoulder pain, frequent urination, and consipation. I know use a cane all the time. I cannot sit or stand or walk without pain. The only relief get is when I lie down but if I move then the pain returns.
